To better understand the aspects of the embodiments of the present application, the following is first described:

(1)5G ProSe UE-to-Network Relay infrastructure

FIG. 1a shows a 5G ProSe UE-to-Network Relay infrastructure. When the UE is out of the network coverage range or the Uu interface signal quality is poor, the UE cannot be directly connected with the network, and the UE with the Relay function can be connected with the network, wherein the UE is called Remote UE, and the UE with the Relay function is called Relay UE. The Relay UE registers in the network, and establishes a Protocol Data Unit (PDU) session and a QoS flow to realize communication with the network. The Remote UE communicates with the Relay UE through a PC5 interface (a communication interface between the UE and the UE), and forwards data through a PDU session and a QoS stream of the Relay UE, so as to achieve the purpose of communicating with a network.

(2) N3 IWF-based UE-to-Network Relay architecture

On the basis of the UE-to-Network Relay infrastructure shown in fig. 1a, in order to ensure end-to-end safety, a UE-to-Network Relay infrastructure based on a Non-3GPP Network Function (N3 IWF) is proposed in the research of the 5G ProSe issue.

FIG. 1b shows an N3WIF based UE-to-Network Relay architecture. In this architecture, the Relay UE is still registered in the network, and a PDU session and QoS flow are established to enable communication with the network, unlike fig. 1, the PDU session of the Relay UE needs to support a connection to the N3 IWF. The Remote UE establishes IPSec connection with the N3IWF through PDU conversation of the Remote UE, and the Remote UE sends NAS signaling messages and user plane data to the network through the IPSec connection.

(3) Connection establishment process of UE-to-Network Relay architecture based on N3IWF

As shown in fig. 1c, the specific process is as follows:

1. the Remote UE and the Relay UE initiate a registration process and acquire a ProSe strategy and URSP strategy information from a network, wherein the strategy information indicates whether the Remote UE accesses to the 5GC through the N3 IWF.

2. The Remote UE executes a discovery process to discover the UE-to-Network Relay.

3. The Remote UE selects the UE-to-Network Relay and establishes direct connection one-to-one communication, and a communication interface between the Remote UE and the Relay UE is a PC5 interface. And if the PDU session needs to be newly established, the UE-to-Network Relay initiates a new PDU session establishment process.

4. And the UE-to-Network Relay allocates an IP address for the Remote UE.

5. The Remote UE selects the N3IWF and determines the N3IWF IP address.

6. The Remote UE establishes an IPSec connection with the N3IWF using an IKE procedure and initiates a Non-access stratum (NAS) registration procedure. After IPSec connection establishment, the Remote UE may establish a PDU session and QoS flow with the network through NAS messages.

In the UE-to-Network Relay architecture based on the N3IWF, a Remote UE establishes a PDU session and a QoS flow between the Remote UE and a Network through NAS information, and the PDU session and the QoS flow are carried on the PDU session and the QoS flow of the Relay UE. As shown in fig. 1d, the transmission of PDUs transmitted between a Remote UE and a Remote UE UPF between a Remote UE and an N3IWF is carried on a PC5 connection (and a PC5QoS stream) between the Remote UE and the Relay UE and a PDU session (and a Uu QoS stream) between the Remote UE and the Remote UE UPF, and to satisfy QoS requirements (such as latency, bit rate, etc.) of QoS streams between the Remote UE and the Remote UE UPF, the PC5QoS stream and the Uu QoS stream of the Remote UE should also satisfy the corresponding QoS requirements.
